Chucker Mode
: This setting allows the lathe to run without the bar feeder. When chosen the
bar feeder sends an auto mode signal to the lathe while remaining in the manual mode.
Feed stop- This signal is used to stop the bar feeder from pushing when bar feeder in automatic
and collet open. Can also be used in the opposite way. The opposite operation would be to not
push at all until the bar feeder is in automatic, collet is open, and feed stop is given. In this
instance it would be use as an M-code feed. Feed stop was/ is generally used in the bar change
process so that the bar feeder does not push before it pulls remnant out of the collet.
If the feed stop is set incorrectly the bar feeder will either not push or push when it should not
be. The M-code that is used depends on the lathe that the bar feeder is installed with. Feed stop
should be set how the customer would like to use it. Make sure to ask.
If the feed stop is operating backwards on Edge products a jumper can be moved to make the
operation opposite.
Door safety- This signal is from the lathe door safety. If the lathe door is open then the bar
feeder should not be able to feed forward. This can also be used like a feed stop depending on
the lathe and bar feeder.
If the door safety is used but not satisfied some bar feeders will not feed. Other bar feeders will
send an alarm for the door safety. If not used then it needs to be jumped in the cabinet.
Edge bar feeders have the capability of changing the door safety in the HMI.
Bar feeder emergency stop- Signal will be sent to the lathe to generate emergency stop on the
lathe.
Often this signal is bypassed by a jumper in the lathe electrical cabinet. To test the functionality,
simple press the emergency stop buttons or other switches that will cause an emergency stop
on the bar feeder. If the bar feeder and lathe are properly set up the lathe should also go into an
emergency stop.
Trouble shooting an emergency stop often requires an electrical book for the lathe to prove out
wire locations or jumper removal. Some lathes are known to have issues with our bar feeder
emergency stops. Relays can be added to change the way the emergency stop is look at.
Power supply- Voltage should always be checked at the lathe plug before the bar feeder is
plugged in. The bar feeder plug wiring should also be checked to the wiring print that is supplied
with the bar feeder. Check wiring of bar feeder plug, check lathe voltage is on the same pins as
